摘要： An optical link module connection system for connecting an optical fiber to an optical link module that performs conversion between an electrical signal and an optical signal. The system is aimed at reduction of the manufacturing cost of printed circuit boards containing those fiber-optic products by allowing an automated soldering process to be applied thereto. The system will also facilitate the product handling as well as storage and improve the board space utilization by shortening the length of the optical fiber. While optoelectronic conversion means comprises a first ferrule, coupling means consists of a second ferrule, a split sleeve, etc. The first ferrule is inserted into the split sleeve in the coupling means so as to contact the second ferrule, thus completing an optical path between a first optical fiber and a second optical fiber. The optoelectronic conversion means will be soldered to a printed circuit board before being joined to the coupling means. That is, when soldering the printed circuit board, the second optical fiber having only a poor heat resistance is not yet mounted on the board, thus allowing automated soldering equipment to be used for the process.

A sealing material is affixed to a cover section in advance. The sealing material is in the form of a film formed by screen printing along the joining portion between a body section and the cover section and having a thickness matching the amount of gap between the body section and the cover section at the joining portion. A conversion device is received in a recess of the body section, and an optical fiber is inserted into the body section from outside along a stepped portion and connected to the conversion device. With the cover section placed on the body section, the two are heated. As the sealing material, soldering paste is used, for example.

摘要： A small-sized magnetic field generator which is suitable for mass production and provides better output stability. A plurality of coils are formed on a non-magnetic insulating material by depositing at least one layer of conductive film in a spiral pattern. A hollow is made in the center of each coil, so that a plurality of main magnetic cores are arranged on the insulating substrate, with their ends fit into those hollows. By supplying appropriate electrical signals to drive the coils individually, their combined magnetic field can be controlled to have an arbitrary distribution. This combined magnetic field is applied to a magneto-optical target device held on the insulating material.
